The Scottish Naturalist. ^3 



Of other Fungi may be mentioned — Ustilago utriculosa, 

 Pucc'mia chrysosplenii, Phyllactinia guttata^ Gcoglossum viride^ 

 Peziza badia, P. Schjunacheri, &c. 



Several other Cryptogams were noticed, including Hahrodo?i 

 Notarisii, on trees at Finlarig. 



At the Business Meeting it was resolved to alter the consti- 

 tution of the Society, so far as related to a public show being held 

 every year. In future the public show will take place at 

 intervals of three or four years, and in such places as shall be 

 deemed suitable. By this alteration of the laws, freedom is 

 given to the Society to have its Annual Conference in localities 

 where a pleasant exploration meeting may be held, but in 

 which a public show would be impossible. 



The following papers were read : — 



ist, "On the Structure of the Hymenium of the Common 

 Mushroom," by Mr. W. G. Smith, F.L.S. 



In this paper Mr. Smith pointed out that Professor Sachs is 

 wrong in stating that the basidium of the common mushroom 

 produces two spores only, and not four, as all other agarics do. 

 Four are produced, but usually only two at a time ; and it is 

 only rarely that more than two may be seen i7t situ at the same 

 time. We will publish this paper in full, with illustrations, in 

 our next number. 



2nd, " On the Geographical Distribution of Fungi in 

 Scotland," by the Rev. J. Stevenson. 



In laying his lists on the table, Mr. Stevenson said — 



At our last annual meeting I laid before you a list of 

 Fungi north of the Tay, and I then promised to supple- 

 ment it by a similar list, embracing the plants which had 

 been recorded for the Flora of the south. 



When I made this promise, I meant to fulfil it literally. 

 But I find that, with the accumulation of materials, my own 

 ideas of what we might not unprofitably attempt have become 

 somewhat enlarged. And I now contemplate preparing lists 

 which may in some measure form a guide to the Mycology of 

 Scotland. By such a guide I think we may supply a want, 

 and at the same time offer a contribution to the more general 

 subject of the geographical distribution of Fungi. The lists, 

 therefore, which I am now preparing embrace the whole of 

 Scotland.
